Be it known that l, NAPOLENH. 'Ser- `noun, a citizen ofthe VUnited States, residl ing at Waltham in the 'county of Middlesex and State of 'B/assachusetts, have invented certain' new and useful Improvements in Plating Half-Rotary'F eed Guides; and l do declare the following to be a. full, clear, and

.exact description of the invention, such as 'will enable others skilled lin the artto which it; appertains to make .anduse the same.

'This vinvention relates to an attachment,

for knitting machine and isknow'n as `a plating half rotary feed guide.

One object offthe' invention is to provide i a device oit-:the character described which may beconnected with knitting machines of a conventional construction .for knitting flat of guides already work thus permitting the attachment to be applied to machines already in use instead rvided,..

Another object ot the invention is to so construct this guide 'that the thread .carrying and guiding portion thereof may be turned at the 'end of each row oknitting before the return movement is started.

Another object-lof the invention is to so constructthis attachment that the hollow thread carrying stem may* be rotatably mounted and at the same Vtimeperl'nitted of being slid vertically out of 'en operative ,position when -so desired, spring means be- 'ing provided to normally retain the thread carrying and guiding stem in an operative position.

Another object ofthe invention is to pro- V yvide improved means 'for limiting rotation of this stem, this means'4 for limiting rotation heing clamped to ,the stem and extending'in eej ` vide an improved bracket having'abutment' opposite directionsbeyond thev stem.

Another object of the invention is to pro-V means forengaging a lever arm and swinging the lever arm to impart rotary'movement to the stem.

, 'Another' object of the invention is t'o so construct this means for turningthe lever rmthat the arm-engaging plunger o r rod may be yieldably held in. a normal position' and'thus permitted. to move under pressure and prevent' breakage.

' This'invention is illustrated in the 'accompanying drawings, wherein:

ing the yarn, carrying and guiding stem This improved attachment is tobe used in connection with a conventional construc- I' tion of knitting machine which is indicated in' general by thefletter M and is not described in detaill as it is to be understood that this is only one specific type vof knitting machine with which the'attachment can be used; rllhis machine includes a bal-B and la 'carriage 4C which moves longitudinally good quality and the second will be a cheaper gradeof 'thread and whenknit the usual manner, the good thread and cheaper thread will be placed one on top the other,4 I

with 'the good thread showing upon the outer face of the material knitted and the Acheaper thread showinguponthe innenface. Other devices are now in usev for guldlng the two threads of yarn so that-a plated yarn formed of threads of diierent quality may be formed but'they are-not as strong and durable as this deviceor as eiiicientin operation.

This attachment is provided with a bracket l--having a lower arm 2 which is bolted to bracket w'ill therefore be'4 securely held in .removed when4 so desiredT and cleaned or has its upper e'nd provided with a head strip 4 which is provided with a socket 5 -at the carriage C by means Aof the bolts 3. The

repaired and then replaced. `This bracket l1-0 one end having a threaded opening formed therein so that the lever 6 may be pivotally mounted by4 mens .ofaf pivot screw 7 which extends through the "bearing 8 of this lever and has its ower threaded end portion screwed. into the suchet 5. The upper and V Passage lower arms 9 and 10 of the bracket 1 terminate in b receive and slidab y and rotatably mount the thread-guiding hollow for the ter portion of its length and as shown c e'arly in Fig. 7, the hollow 14 which forms a thread passage extends from the upper end of this stem to a point beneath the lower 12. Thelower portion of this stem. is out from onev side -to provide a reduced neck portion -13 which is shaped in cross seeh'on as shown 1n Fig. 4 and at its lower end carries a. head 15' having longitudinally extending openings 16 formed therein-and leadingrom its upper end to one side of the neck 13'Y toits lower end. Therefore, the yarn can be passed through the passage 14 and along the flattened face o theneck 13 and then passed through the openings 16, the good grade of yarn belng these oepings and the cheaper yarn being paed ough the second opening. By havmg. the stem provided with the neck. 13', the threads after being passed through the passage 14 een be very through the openings 16 in the head 15. The upper endc porhon of this stem 13 is threaded and carries a" collar 17 which is screwed upon the -upper end portion ofthis stem togthe desired point and then anchored by means of a set-screw. A washer 18 is provided beneath-this collar 17 to engage the face of the upper bearing ll-and thus prevent wearing. of the lc l lar. Above the collar 17, there is provided a gear 19 which is screwed into place and anchored by means of a set-screw which passes through the reduced upper portion 19' of this 'gear or pinion. This 'gear or pinion meshes wi a rack 20 provided at the end of the operating handle or lever 6 and it will be, readily lVhen 'this stem. 13 receives movement, it is only desired to have it rotate for approximately one-half of a revolution.

' Therefore, there has been provided an abutment-yokefor har 2L` This yoke vor bar 21 is positionedY to extend ansversely of the stem. above'the lower bearing 12 and upon the opposite side of the stem,there has been provided a clamping bar 22. These bars 21 and 22 are seated in notches formed in opposed'sidcs of the stem and'cljamping screws 23 are' passed through openings formed in the clampigg bar 22 and screwed into openin@ form in theyoke 21. Fromnu inspm'onofFigjtwillbereadily seen sleeves 11 and 12 which' stem 13. This stem 13 isassed` through one of easily threaded support sem that when the lever is swung upon its pivot 7, rotary movel Ament will be imparted to the stem 13.

Leonesa comparing Fig. x8 ,with Fig. 9, it will .be readilyseen that the stem free to rotate' :for approximately a one-half revolution, ro-

tation being stopped by en gement of the -abutment screws 24 with t `e sides v'of the bracket.v It will be'further noted that if it is found that with the yoke bar set as shown, the stem turns a little more than desired or not quite enough, the abutment pins or.

screws 24'can be adjusted and then locked in the proper place by the lock nuts 24;.

It is sometimes desirable to. permit the"v stem to be moved upwardly out of the way and therefore this stem may be moved u wardly through the bearings 11 and 12. 'llt is of course however desired to have the stem normally remain in the lowered or operative position with its pinion meshing with the pinion of the rack 20. Therefore, there has been provided a spring .25 whichis coiled about thev stem between the' upper and .lower Y bearings with its upper endY 'engaging a bearing washer-.26 which bears against the lower end of thefbearing 1 1 ami its lower end vengaging.; a bearing` washer 27 which bears against the upper edgesof the clamp-- ing bar 22 and yoke bar 21. With this spring in place, thestemv-will be normally held in A the lowered or operative position shown but can be readily moved upwardly against the action of the spring when so desired and either held inthe raised position by vhand against the l the stem in the iraisedposition. It will thus be seen that the stem be slidably and rotatably mounted and further that there has been provided a leverby means ofwhich-the stem canbe for one-half ofa revolution. f y v This stem is to be when Ithe carriage reaches each end of its path of movement and is about toma-ke al return movement. swung and .turn

providedi a bar or, rod 28 which extends In order to permitfthe lever-to be the stem, therehas been t for can be turned to the proper position to permit the teeth of thefpinlon 519 to press teeth of the rack\bar`20 and thus longitudinally of the .knitting machine and at one end is provided with a supporting.

bracket 29 which is the form of curved arms, the upper ones of which are connected withthe bar or rod .28 and the lower ones of which are secured to the bar B lby suitable fasteners; At eaehend, there lhas -been provided an abutment for engagement'by the lever 6 so that when the carriage approaches lever will be swung upon its pivotand rov .Leonesa each end of itsjxtentof movement, the

tary movement impartedtothe' stem. l1.; of these abutments is in the form of a pin or plunger 30 which is slidably mounted in ears 31 carried by the baror strip 28 andprovided with a head 32 for engagement by the lever 6. A spring 33is positionedbe-A tween the ears 31 and lserve to yieldably hold the abutment pins against sliding -movementbut permit of sliding movement ywhen the pin is engaged vby the lever arm. Therefore, the lever arm can be swung to im art rotary movement to the stem without anger of' breakage due to excess pressure being applied'to the lpin or turning of the .stems stopped' before the carriage has extent of movement in 'the handle will engage the' heads lof the plunger 30 of these abutments thus causing -the levenarm to be swung upon its pivot and Aturn the thread carrying and guiding' s tem as the carriage reaches the-end of its movement in either direction. The stem will thus be rotated for a half'turn priorjto a return movement in either direction anditherefo're the threads will be kept in the proper relation to eachother, so that the 'article can be 'knitted with -a plated yarn having `the good yarn positioned outermost and showing. from the outside and the cheaper yarn innermost and 'showing from the inner' or. underface of the article.
